Embodiment Construction

[0017] figure 1 It is an overall system diagram of a vehicle equipped with the parking lock control device of the embodiment. The vehicle of the embodiment is a rear-wheel drive electric vehicle, and has front wheels FR, FL as driven wheels and rear wheels RR, RL as drive wheels. The rear wheel RR on the right side of the vehicle is provided with: an in-wheel drive motor MR (right side motor) that directly drives the rear wheel RR, and a parking system that can lock the rotation shaft of the drive motor MR to the vehicle body side. Lock mechanism PLR, resolver NR (vehicle behavior detection device) that detects the rotation speed (or rotation angle) of drive motor MR. Similarly, the rear wheel RL on the left side of the vehicle is equipped with an in-wheel drive motor ML (left side motor) that directly drives the rear wheel RL, and a parking lock that can lock the rotation shaft of the drive motor ML to the vehicle body side. Mechanism PLL, resolver NL (vehicle behavior dete...

Abstract

This parking lock control device for a vehicle activates either one of a plurality of parking lock mechanisms when a parking lock activation command is output. In this state, the movement of the vehicle is estimated or detected, and if the movement of the vehicle is greater than or equal to a predetermined amount, a torque for inhibiting the movement of the vehicle is generated by a motor connected to the other parking lock mechanism. Thus, power consumption associated with the parking lock is reduced.

Description

technical field [0001] The present invention relates to a parking kock control device for locking wheels. Background technique [0002] Conventionally, Patent Document 1 discloses a configuration in which, in a vehicle including a motor for each wheel, each wheel is provided with a parking lock mechanism, and when a parking lock request is output, the parking lock mechanism for each wheel is The mechanism moves to lock the wheels. [0003] However, when a plurality of parking lock mechanisms are activated, there is a problem that the amount of power consumption is large. [0004] Patent Document 1: (Japanese) Unexamined Patent Application Publication No. 2007-314036 Contents of the invention [0005] An object of the present invention is to provide a parking lock control device for a vehicle that can suppress power consumption. [0006] In the parking lock control device for a vehicle according to the present invention, when a parking lock operation command is output, e...
